Help with Layout and ball reaction
« on: February 13, 2009, 07:57:13 AM »
First, excuse my pic. It was the best I could do with MS paint.

I would like to know what would be the different ball reactions from the three layout/pin positions and why.. Red, green , blue.

I'm pretty sure the blue would get down the lane the most and be sharper on the back. More skid flip. And the red would be sooner and smoother. My question really is does the angle of the pin to cg in relation to the angle of the track have anything to do with the ball reaction?
example.. the blue pin to cg is going toward the track and the red pin to cg is kicked out going toward the PAP. So in the Blue the weight would be on the outside of the core's rotation and the red the weight would be on the inside of core's rotation.

This is on a a symmetrical ball. I know it may make more of a difference on a mass bias ball.  But even on an assymetrical.. would a 70 deg drill angle be different if it was towards or away from the track angle?  Or is it the actuall distance of the MB/PSA/Rg to the PAP that matters.

mo pinels dual angle layout technique explains the significance of all the angles and postions and stuff. its on the morich site under mo's corner. very in depth and very confusing to someone who doesnt know alot about layouts and drilling a bowling ball

This is a very good article and his techniques have worked for the bowlers that have allowed me to use them (most customers come in with the drill sheet and ask for a layout from it).  If you're not actually going to layout and drill the ball yourself, just go to the last page or two and read the section on how to apply the technique to selecting a layout.  --  JohnP

Thanks for the help.. I actually know a decent amount about laying out a ball and do the layouts for most of my equipment.  I am just trying to learn and always question tequniques and the way things are done.  Example.. it is amazing that just in the last 10 years pin to pap has been used.  All of the years before that it was just based on trial and error and pin location in relation to the gripping holes.
I'm just looking for the scientific/physics (true way and reason) a ball does what it does.

The pin to PAP distance determines the percentage of potential flare that is realized.  3 3/8" is 100%.  From 3 3/8" to 0 the flare decreases to a minimum and the ball breaks earlier.  From 3 3/8" to 6 3/4", the flare decreases to a minimum and the ball breaks later.  Practically, to avoid reverse flare the range used should be 3/4" - 6".  --  JohnP
